Installation
Loosen the 4 screws at the top of the head and rotate the head direction to select the appropriate operating key hole position before installation.
When installed in flush doors, it needs to be larger than the minimum radius.
Please install the switch and operation key within the prepared position range (1 to 3.5 mm).
The permissible error in the installation of the operating key is within ±1mm from the center of the operating key insertion hole.
